The Pyrometer Digital 500 II digital thermometer is a rugged portable easy to read thermocouple pyrometer that utilizes interchangeable, reusable thermocouple tips for both surface and immersion applications. This digital thermometer pyrometer is ideal for temperature measurement using thermocouple thermometer K type thermocouples. Instrument temperature measurement accuracy to ± 1.0% of reading is achieved by employing an automatic internal cold end junction compensator to prevent temperature measurement errors due to ambient temperature variations. The Digital 500 thermocouple thermometer comes complete with a durable Lexan housing and is ready to use with a wide variety of optional rigid & flexible extension arms and thermocouples.
